If your phone has Composer, you can enter one ringing tone of your own by inputting the text from freefonefun.co.uk into your composer.

Creating a new ringing tone
When you enter this function, the tone that you created previously is shown, if available.

To enter a new or edit an existing tone:

1. Enter the desired notes

Press:

1 for note c
2 for note d
3 for note e
4 for note f
5 for note g
6 for note a
7 for note b
0 for a p (pause = "Rest")

The phone plays each note after it is entered (unless the phone tones are off).

2. To adjust the characteristics of the note, do as follows:

Note duration: 8 shortens (-) and 9 lengthens (+) the duration of the note or rest. The default duration is 1/4. The duration is shown in front of the note, e.g. 16d denotes a note d with duration1/16.

Rest: 0 inserts a rest (i.e. pause) of the same duration as the previous note.
The default duration of a rest is one quarter note (1/4).
The rest is indicated by the - character.

Octave: *+ sets the octave for new notes. The octave is shown as a number after the note (e.g. e1).

Pitch: # makes the note sharp (indicated by # in front of the note), e.g. #f. The pitch selection is not available for notes e and b.
